uint32_t Atomic::generic_compare_and_swap	(	volatile uint32_t *	p,
		uint32_t	oldval,
		uint32_t	newval
	)

A generic atomic compare and swap for 32-bit integer values.

This function is using a mutex to provide atomicity.

Parameters

p	Pointer to memory address.
oldval	Old value to be expected.
newval	New value to be stored.

Returns

value of the memory location before the store

Definition at line 48 of file atomic.cpp.

uint64_t Atomic::generic_compare_and_swap	(	volatile uint64_t *	p,
		uint64_t	oldval,
		uint64_t	newval
	)

A generic atomic compare and swap for 64-bit integer values.

This function is using a mutex to provide atomicity.

Parameters

p	Pointer to memory address.
oldval	Old value to be expected.
newval	New value to be stored.

Returns

value of the memory location before the store

Definition at line 77 of file atomic.cpp.

void * Atomic::generic_compare_and_swap	(	volatile void **	p,
		void *	oldval,
